SI-IEVE CARRIER FOR ENDS OF 7CURJIAIII' RODS.

Application filed August', 11925. Serial No. 48,484.

'This invention relates to curtain and drapery rods and more particularly .to hollow, longitudinally slotted rods of this type, adapted particularly to be mounted upon the top wall of a window-casing, door-casing or passageway and which are equipped .with drapery carriers or slides for the suspension of so-called pull-string7 draperies which are adapted to be separated and brought together for admitting or shutting ott light and air from windows and opening or obstructing door and passage-ways.

The present invention relates more particularly to the sheave carriers for rods ot this type and to the drapery carriers or slides and has i'or its object to provide sheave carriers which are telescopically associated with the ends of the rod and so dispose the sheaves as to cause the cord trained over all of them to be disposed, except as to its depending end portions, substantially entirely within the rod.

A further object of the invention is to provide a sheave carrier which is so constructed that it may be very easily adapted to receive a pair of sheaves rotatable on a horizontal axis or a single sheave rotatable on a vertical axis.

A further object of the invention is to provide drapery carriers for rods of the type aforesaid and equipped with sheaves disposed to eilect housing` of the main portion of the cord within the rod, which are equipped with means for attaching the cord thereto without requiring knotting of the latter and wherein said means are so disposed as to obviate projection of the cord 'from the slot of the rod.

The invention is fully illustrated in the accompanying drawings, wherein Fig. l is a view in sideelevation of a curtain or drapery rod equipped with devices constructed in accordance with my invention, the same being shown as mounted in the top .of a window-casing or the like.

Fig. 2 is a bottom plan view ofthe rod.

Fig. 3 is a transverse section on the line 3-3 of Fig. l.

Fig. l is a central, vertical, longitudinal section on the line 4 4 oi' Fig. 2.

Figs. ,5 and 6 are sections on the lines 5-5 and 6*-6, respectively, of Fig. 4.

Figs. 7 and 8l are perspective views of the respective sheave carriers for opposite ends of the rod.

The rod l is of the conventional flat or VC-sl'iaped type provided with a continuous ylongitudinal slot. The latter is bordered by iianges 2 upon which the drapery kcarriers 3 and 4t are supported. In the wall of the rod `opposing' the slot'there are perforations for `the passage oi? screws 5 for securing t-he rod to the top wall of the casing.

The drapery carriers 3 are known as master-slides or master-carriers and are secured to the upper corners of the meeting edges oi the pair of draperies or curtains which are also secured along their upper edges to the carriers 4.

The carriers 3 are adapted to be secured to the cord 6 between the ends of the latter as hereinafter described. Said cord 6 has two depending end portions each of which 4carries a weight, the lat-ter being indicated at ,7 and 8, respectively, said end portions depending from the pair of sheaves 9 over which the cord is trained. These sheaves are disposed at one end of the rod 1 and are rotatable on a horizontal axis while the sheave 10 at the other end of the rod is rotatable on a vertical axis, the cord being also trained over said sheave 10. The latter is of a diameter slightly exceeding the width of the slpt of .the rod, the sheaves 9 and l() being relatively disposed so that the cord, when taut, will extend substantially parallel with the flanges 2 and substantially midway between the latter and the top wall `oil the rod or, in other words, substantially axially of -tlie curved side walls of said rod.

That portion ot the cord 6 extending from one of the sheaves 9 to the sheave 10 Y is secured to one of the master-carriers 3 and that portion of the cord passing` from the other sheave 9 to the sheave l() is secured `to the other carrier 3. The said respective portions of the cord always travel in opposite directions so that upon lowering :the weight 7 for example, the meeting edge- :portions of the curtains or drapes will move ed mouth portions. The cord is drawn in a loop through the slot 11 and said loop passed over the projection 14, the cord being forced through the contracted mouths of the recesses 13 to prevent disengagement ofthe loop from the projection 14. The edges over which the loop 15 passes are all sharp and act to resist slippage so that there is no lost motion between the cord 6 and the carriers 3. V i

The sheaves l.) and 1() are carried by memhers 16 and 17, respectively, which are identiral and formed with the same dies except as hereinafter' described. Each thereof includes a body portion of a shape similar lo that of the rod 1 and of a size to snugly teiescopieally receive an end portion of the latter. Said body portion is provided with a longitudinal slot 18 for the passage of one of the screws :3 and permitting of adjustment of the member 1G or 17 on the rod to a limited extent. rlfhe top wall of each of said members projects at one end beyond the side flanges thereof and terminates in a downwardly extending end-flange 19 provided with a perforation 20. The projecting end portion of said top wall is also provided with downwardly extending side flanges 21 having extension portions-22 the extremes of which oppose the side edges of the flange 19. Said flanges Q1 and extension portions 22 are provided with perforations 23 and 24, respectively, the former being adapted to receive the pivot pin 25 carrying the sheaves 9. A spacing plate 26 secured to the projecting end portion of the top wall by welding or other suitable means, projects between the sheaves 9 and is provided with a perforation to receive the pin 25.

The member 17 is devoid of the plate 26 and has the projecting end portion of its top wall bent between its ends to cause the flange 19 to extend parallel with said top wall and bring the perforation 2O into alignment with a perforation in said projecting portion of said top wall. The sheave 10 is disposed between the latter and said flange, the pivot pin 27 of said she-ave being mounted in said perforations.

Before mounting the rod 1 on the casing, the carriers 3 and as many of the carriers 4C as may be required, are mounted on the rod and the members 16 and 17 mounted on the ends of the latter. The cord 6 is either then passed through the rod and trained over the sheaves or, preferably, this is done before the carriers are disposed upon said rod by passing the cord over the sheave 10 and then inserting it into the rod through the slot in the same and then passing the end portions of said cord over the sheaves 9. This can be easily accomplished without mounting the members 16 Vand 17 on the rod or by temporarily mounting the same and then removing one thereof and inserting the carriers and replacing the demounted member.

j The rod is then mounted on the casing, the weights 7 and 8 secured to the ends of the cord and properly positioned with respect to each other. The master-carriers 3 are then moved to the middle of the rod and the loops 15 drawn through the slots 1l by means of a suitable device such as a buttonhook, said loops being then engaged with the projections 141-.

lhe curtains or drapes are then secured to the carriers 3 and et and the outer upper corners thereof secured to the extension portions 22 of the flanges 21 by means of the perforations 2l.
